Around last seconds I got just mV hardly and I stopped heating I do not want to waste parts actually. I heated its one lead almost 45 seconds I was thinking the diode is going to blast, but it’s fine still. Started by fastline Yesterday at 8: A datasheet for the 1N34A germanium diode said its forward voltage is typically 1V at 5mA which is much too high.

Here in The West there are so many radio stations that a crystal radio is too simple and picks up a few stations at the same time. I am searching something can replace these transistors: To get the radio working the diode need to heat up in such bad way, the diode would not be able to survive more minutes.


In order to better serve you, please access the online inquiry system. Willen Well-Known Member Oct 25, I will try all stuff to find what is the best: A Central sales representative will confirm the availability of the plating type requested.

Click to view availability. So nice part is to make temperature sensor!

2N4001 Datasheet

Voltage drop was mV at first and got around mV just after around 10 seconds of heating. For a better experience, please enable JavaScript in your browser before proceeding.

A red LED biased with 1. You dztasheet also try biasing it with a little DC to help get the dynamic forward voltage down.

So for your crystal radio you would need a germanium. I am in Canada not the OP and the weather is lovely today, no frost and no snow yet. The original poster cannot buy ordinary electronic parts because he is a kid living far from a city datasheeet Vietnam. Electrical sparks car spark plugs or electrical switching and lightning are heard. The 1N silicon diode typically is 0.

The transistor amplifies the changes in the 24n001 voltage of its base-emitter diode. For further assistance using the new web based request system, click here.


I don’t know why you are having trouble finding the 1N34 diode. I have no temperature meter.

Semelab Plc. 2N Datasheet.

I have ft antenna but can longer to ft. Alternate Devices with Different Packaging:. Here are the instructions how to enable JavaScript in your web browser. They also make fast low datasheett Schottky diodes for small signal high frequency use. Performance depends on your antenna and earpiece too. The change in forward voltage of a silicon not silicone which is a synthetic rubber diode when its temperature changes is what causes a poorly biased transistor not to work properly it is a temperature sensor.

What makes the 1N34 different is the low forward voltage drop, on the order of. Login to the website is required. Using Google, this was the first link on my search results.

The current in a crystal radio is much less then the forward voltage will also be much less so I found the datasheet 47 years old! I just used an cellphone earpiece plays little louder than others and got loud audio like a volume 1 of my cellphone.
